Comment (by alpmestan):

 I have a GHC patch
 [https://github.com/alpmestan/ghc/commit/f78e0ae443f48bb2c58819f04d781a3d27c2d528
 here].

 I also opened [https://github.com/snowleopard/hadrian/pull/701 an hadrian
 PR] to verify that this works as expected. When I get it to pass, I'll
 submit a differential.
